PMMIF - Performance: Phosphomannomutase (PMM) and Phosphomannose Isomerase (PMI), Fibroblasts

Test Catalog

Test ID: PMMIF    
Phosphomannomutase (PMM) and Phosphomannose Isomerase (PMI), Fibroblasts

Method Description Describes how the test is performed and provides a method-specific reference

One confluent T75 flask of fibroblasts is harvested and the cell pellet is subjected to 1 freeze-thaw cycle. The lysate is collected and the enzymatic activity for both phosphomannomutase and phosphomannose isomerase is measured by a colorimetric assay.(Personal communication: Dr. Otto van Diggelen, Erasmus University, Rotterdam, The Netherlands)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.


Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

30-45 days depending on rapidity of growth

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

3 years - Check with the lab for availability

Performing Laboratory Location The location of the laboratory that performs the test
